Vibratory Finishing
The treatibility required no pH adjustment from the initial 7.5 pH. The treatment required 0.15 grams of Floccin-J in a 100 ml sample. The dosage equates to a treatment of 12 lbs/1,000 gallons. Based on $1.25/lb for Floccin-J, the treatment costs will be about $15/1,000 gallons = 1.5 cents/gallons. Based on the water clarity, the facility might be able to reuse the water and reduce their fresh ...

Efficiency Removal of Phenol, Lead and Cadmium by means of UV/TiO2/H2O2 Processes
A variety of processes can be used in treatment of industrial wastewaters. The relatively newest of which is photo catalysis with titanium dioxide which may also be used plus hydrogen peroxide to improve the treatment rate. In this study, photo catalysis/ hydrogen peroxide processes had been employed for the removal of phenol, lead and cadmium by three different pHs of 3.5, 7 and 11. The ...

Removal of surfactant from industrial wastewaters by coagulation flocculation process
Surfactants are among the most widely disseminated xenobiotics that contribute significantly to the pollution profile of sewage and wastewaters of all kinds. Among the currently employed chemical unit processes in the treatment of wastewaters, coagulation-flocculation has received considerable attention for yielding high pollutant removal efficiency. Jar-test experiments are employed in order to ...

Getting back to basics: What is pH?
Getting back to basics: What is pH? The most used measure in wastewater treatment, and for good reasons The “potential of hydrogen” or “pH” is the measure of free hydrogen activity in water and thereby indicative of the measure of its free acidity or free alkalinity. Gauged on a numeric scale of 0-14, solutions with a pH of less than 7.0 are acids. Solutions with a pH ...

Small town SCADA yields big-time results - Case Study
Rural county now able to monitor & control pumps, gather valuable data in real time Marlboro Water Co. (MWC) is a small water utility nestled in the Pee Dee area of South Carolina, a region rich with natural resources—including freshwater streams, forests dense with hardwoods and abundant wild game. MWC acquires water from the Middendorf Aquifer, which supplies five groundwater wells ...

Effect of aluminum-containing amendments on phosphorus sequestration of wastewater treatment Wetland soil
Little research has been conducted on methods to restore the P removal capacity of older constructed wetlands, as P treatment capacity can decrease with time. We investigated the capacity of alum and three Al-containing alternatives (alum residual, polyaluminum chloride [PAC], and partially neutralized aluminum sulfate [PNAS]), at three rates (9, 18, and 36 g Al m–2) to reduce P concentrations. ...

Use of chemically treated sawdust for chromium removal from aqueous solutions: effect of process parameters
This paper reports the effect of various process parameters on the removal of chromium from aqueous solution using formaldehyde–treated timber industry waste (sawdust). The adsorbent was characterised by Scanning Electron Microscopy (SEM) and Energy Dispersive X–Ray Analysis (EDAX). Influence of chromium concentration, pH, adsorbent dose and contact time on chromium removal from aqueous solution ...

Effect of the rotifer
Lecane inermis, a potential sludge bulking control agent, on process parameters in a laboratory-scale SBR systemThe influence of a high density of rotifers, which is known to be able to control filamentous bacteria, on the parameters of an activated sludge process was examined in four professional laboratory batch reactors. These reactors allow the imitation of the work of a wastewater treatment plant with enhanced nutrient removal. The parameters, including oxygen concentration, pH and temperature, were ...

Latex Paint Manufacturer-3
Integrated Engineers, Inc. did the following treatability on the wastewater produced at a Latex Paint manufacturing facility. The treatments required no pH adjustment. The best product was treated with 0.3 grams of Floccin-K in a 100 ml sample and required moderate mixing (1 minute). The dosage equates to a treatment of 25 lbs/1,000 gallons. At an end consumer price of $2.00/lb., the treatment ...

The ORP and pH profiles during simultaneous nitrification and denitrification of low carbon municipal wastewater
The ORP and pH profiles and the stability of Simultaneous Nitrification and Denitrification (SND) for low carbon municipal wastewater treatment were investigated under the different aeration modes in Sequencing Batch Reactor (SBR). The results showed that the 92% removal efficiency for TN, the smallest average level of ORP and both of the variation of ORP and pH values are achieved in ...

Effect of brookite presence on nanocrystalline anatase – rutile phase transformation
TiO2 nanocrystals were prepared by hydrolysis and peptisation of titanium isopropoxide under different pH values. The as-prepared powder of very fine anatase crystallites ranges from 8 nm in acidic solution of pH 3 to 10 nm in basic solution of pH 8. Heat treatment of the powders leads to grain growth and anatase-rutile transformation. Experimental results have shown that the anatase to rutile ...

Laboratory Study of Conventional Alum Treatment versus MIEX® Treatment for Removal of Natural Organic Matter
EXECUTIVE SUMMARY In recent years, considerable effort has been made in drinking water treatment research to develop methods with improved natural organic matter (NOM) removal from water. Reduction in the level of NOM before disinfection can minimise the formation of disinfection by-products and reduce the residual required to control bacterial regrowth in the distribution system. This ...
